They have been coiled up on an expansible mandrel, and after coiling,have been tied with wire or a metal strap (l in Fig. 10), as is theusual practice. After this, the expansible mandrel has been contractedand the coil removed for packaging.

In making my package, my first step is to provide a pair of skids 2 and3 in Fig. 3, preferably formed of wood and preferably beveled at theirends as shown. .These skids are fastened in interspaced position by acrossing pair of sheet metal members 4 and 5. Beneath thesesheet metalmembers I prefer to place bands 6 and I subsequently to be used in theformation of the coil package.

The structure shown in Fig. 1 is preferably formed by securely nailingthe members 4 and 5 to the skids'2 and 3. The ends of the members 4 and5 may terminate at the edge line of the coil which is to be placed onthe skid structure, or they'may be so formed as to project beyond theside edges of the coil. Where this is done, in the subsequent packagingof the coil, the ends of the members 4 and 5 may be bent upwardly andwill serve in part to give edge protection to the coil. As shown in Fig.2, the next step is to place over the structure of Fig. 1, a sheet 8 ofpro- 9 Claims.

My invention relates to means for packaging and shipping heavy coils ofsheet metal. The method and package were devised particularly for usewith coils of silicon steel in strip form; but it will be evident to theskilled worker in the art that they are applicable to other coilspresenting similar problems.

It is an object vof my invention to provide an adequate, secure,packaged coil for handling, storage and shipment. I

It is another object of my invention to provide an inexpensive packagestructure, yet a structure which gives adequate protection from theweather as well as from mechanical hazards normally encountered inshipment.

Still another object of my invention is the provision of a packaged coilwhich can be handled as a unit either by truck means or by means of anelectro-magnet attached to a crane or the like.

Still another object of my invention is to simplify the formation ofckaged coils in ways which will hereinafter be s t forth.

Still another object of my invention. is the provisionpf a packaged coilsuitable for railroad shipment in a gondola or box car without bracingor the like.

Further objects of my invention will be pointed out hereinafter or willbe apparent to one skilled in the art upon reading these specifications;and these objects I accomplish by that certain construction andarrangement of parts, and in that certain method of which I shall nowset forth an exemplary embodiment.

Reference is made to the drawings, wherein:

Such a structure is illustrated inFigs. or from the welding plant in the ordinary form. 3 and 4, and maycomprise interspaced wooden ible substance desired. I have found itentirely satisfactory. to use a water-proof fabric formed of two layersof heavy paper cemented together by means of asphalt and having betweenthem long, strengthening fibers usually of jute or sisal; but othermaterials will serve as wrappings such as multiple layers of papercemented together with a water-proof adhesive, treated cloth or otherrubberized fabrics, paper reinforced with cloth, etc.

It facilitates the formation of my package, as will hereinafter be madeclearer, if the sheet is of such size as to cover the cylindrical partof the coil and overlap the coil on its top edge. Over the sheet 8 andover the structure of Fig. 1, I prefer to place a resilient and fairlystifl disk 9. This disk may be made of various substances 1n eludingmetal; but I have found it entirely satisfactory to use a disk ofordinary corrugated board such as that used in the manufacture ofshipping cases. A double lined corrugated sheet cut of circular form, ormultiples of this structure, serve very well. The structure of Fig. 2 isnow ready to receive the coil.

tective material. This sheet may be of any flex- 'fourths inch stock.One or more of these disks may be used at each position in the'structureof Figs. 3 and 4. The strips I2 may be say threeeighths inch inthickness by one and five-eighths inch wide, and of a length appropriateto the length of the coil. The members 2 and 3 of Fig.

1 may for usual sizes of coils, be cut from 2 x 4 lumber. The coil 13containing the core structure, is next placed upon the disk 9 in aposition which will be clear from Fig. 8. When this has been done, thesheet 8 is folded up around the coil so that the package assumes theappearance shown in Fig. 5. It will now be clear why it is advantageousto have the sheet 8 big enough to cover the outer sides of the coil andextendover the top thereof, since the structure, of Fig-5 issubstantially self-sustaining, and no fastenings for the sheet 8 arerequired during the application of the outer wrapping.

, As shown in Fig. 6, an outer wrapping, longer in length than the coil,is next wound around the coil. This outer wrapping is indicated at M andis preferably held in placeby a band or tie IS. The end of the sheet Hwhich projects above the coil is next neatly folded down on top of thecoil as shown.

Finally a disk I 8, similar to the disk 9 may be placed on top of thecoil as shown in Fig. 7. Edge protecting means I! may be put in place asshown. These edge protecting means may be solid fiber or other cardboardsubstance, or may be of metal. The strap members 8 and 1 are nextbrought up the sides of the coil and across the top where they arefastened in ways known to the art. The coil structure is now complete,

' and ready for shipment.

It will be noted that the coil is completely encased in a water-proofwrapping and that the wrapping is so disposed as to make the coilrainproof. As a consequence a series of these coils may be placed in agondola car in somewhat interspaced relationship, and transportedwithout difliculty in spite of adverse weather conditions.

In Fig. 9, I have shown a type of top structure which while not as neatas the disk [6, is some times found ofadvantage. particularly where amanufacturer is engaged in packaging and shipping a wide variety ofsizes or coils. Under some circumstances to attempt to-provide a disk l8accurately cut for all sizes of coils, would require an uneconomicalinvento y- The device of Fig, 9 consists of a semi-circular body I8 ofcorrugated board or other substance, the outer edge portion of which isprovided with tabs or ears IS. A pair of these members in opposedrelationship may be substituted for the disk It, the meeting edges ofthe members substantially following a diameter of the coil. The tabs l9may be bent over the top circular edge of the coil, to a greater or lessextent, as may be desired. Any-pair of these members may be employedwith coils which difi'er considerably from each other in size, so thatthe number of different sizes of top members required is greatly cutdown. Where any great length of the tabs I 9 is bent over the circulartop edge of the packaged coil, it will contribute to the neatness 0f thepackage to pass a band around it near its top edge, so as to hold downall of the flapsv I9. Where a pair of the members of Fig. 9 are to beused with a relatively small coil, these members may be overlapped atthe center-of the package, as will be clear.

Modifications may be made in my invention without departing from thespirit of it,
